The first 3 panels were presented one to stay at company HQ, one to the San Jose tech museum, and one to be auctioned by eBay (not!, <a href=\"https:\/\/www.nanosolar.com\/blog3\/2007\/12\/21\/ebay-cancels-our-panel-2-auction-due-to-charitable-angle\/\" target=\"_blank\" >read the blog on that story&#8230;<\/a>)<br \/>\n<br \/>\nWe&#8217;ve been a bit bearish on photovoltaic solar for two primary reasons: cost and capacity. If the breakthroughs claimed by Nanosolar prove out in practice (there is precious little technical information available about the printed solar cells performance) then it&#8217;s possible the cost aspect of our bearish outlook has been cracked. The pricing places these panels in the capital cost class of plain coal (as opposed to &#8220;clean coal&#8221;) and natural gas fired technologies. That is significant.<br \/>\n<br \/>\nThe capacity aspect is still problematic, here in North America around 40 degrees north, one can expect an average capacity factor in a good solar location to come out at 24%; peaking at ~36% in the summer and bottoming out at ~12% in the winter. When looking at solar relative to fossil fuels, hydro, nuclear, and geothermal, all baseload technologies, this aspect is still a barrier. However, at the new price point, the major advantage solar pv has is in small, distributed installations which are impractical for the baseload technologies and that advantage can now be maximized.<br \/>\n<br \/>\nThe missing link is the technical details. State-of-the-art pv loses around 1% efficiency per year of use, is that true of <a href=\"https:\/\/www.nanosolar.com\/\" target=\"_blank\" >Nanosolar<\/a>? What is the conversion efficiency? Silicon-based pv cells have gone north of 40% in the lab and are commercially available around ~20%. Thin film cells check in around 10%. Based on what has been disclosed about the technology it&#8217;s likely to be closer to thin film than silicon in efficiency. Until these details become clear and the breakthrough can be judged publicly against known technology, it&#8217;s exciting potential. We&#8217;ll be anxiously waiting to see the details.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Photo Credit: Nanosolar Blog Last week, much ink (pun intended) was spilled regarding Nanosolar&#8217;s announcements regarding their new printed solar cell technology.
